+1 to what Josh writes below. I would also differentiate between mobile networks (service provisioned to individual devices & often carrier s/w on the device) and wireline networks (home devices behind a router/gateway/NAT). I just don't think sale of data is a business for wireline ISPs. If it were - given most companies are public - you'd see it in SEC 10K filings and on earnings calls. Indeed, they'd be required to talk about it with investors if it was a material revenue stream. I see none of that. Rather, the focus is on subscription revenue. If you want to know about data monetization - focus on services you don't pay for...

Our ISP does not collect (nor obviously sell) customer information/traffic. People volunteer all of their information on Facebook/Twitter/etc already, I'm not sure I see a concern.

I'm pretty sure that they can be compelled to do that, but do they do it for their own reasons too? Or is this way too much overhead to be doing en mass? (I vaguely recall that netflow, for example, can make routers unhappy if there is too much "flow"). Obviously this is likely to depend on local laws but since this is NANOG we can limit it to here.
